Ringkopbouten

Ringkopbouten, or ring head bolts, are fasteners featuring a circular ring as the head, designed to provide a secure point for attaching ropes, chains, or hooks. The ring is typically incorporated into the bolt’s head and serves as an attachment point for lifting, rigging, or securing loads. They are used in lifting and rigging, as anchor points in construction, and for securing loads in industrial settings. Common variants include through-ring bolts, where a shank passes through a hole and is secured with a nut, and ring-head bolts with a threaded shank that engages a tapped receptacle.

Materials and finishes: ring bolts are usually made from carbon steel or stainless steel; finishes include galvanized zinc plating or stainless finishes to resist corrosion. They come in a range of diameters and thread lengths, with load ratings varying by material, diameter, and configuration.

Applications: they create fixed lifting points on machinery, structural steel, or timber; they act as anchor points for chains or slings; in some designs the ring is welded onto a bolt for permanent installations.

Installation and use: select a ring bolt rated for the expected load and direction of pull; ensure the load is applied in line with the bolt axis to avoid bending; use appropriate mounting hardware (nuts, washers) where required; for timber or concrete installations follow manufacturer guidance for embedment depth, hole size, and edge distances; inspect regularly for deformation, corrosion, or loosening.

Safety and standards: ring bolts are load-bearing devices and should be installed and maintained according to relevant standards and safety guidelines; do not use damaged or deformed bolts and replace them if compromised.
